I chose Google Code because I thought it more likely that someone searching for something like this would find it there than anywhere else. See code.google.com/p/statistics-distributions-js for the project.
That was my original thought, but JSAN is a dead project at this point.
Yeah, I didn't know JSAN was dead (shows you how often I used it), but it is as dead as a doornail. That's too bad, I think that would've been nice to have.
My problem with promoting it that way is that I would be drawing attention to it for people who don't want it, and people who do in 6 months still can't find it. Even if there is no centralized repository, is there any reasonably popular and searchable one?
Well, this sites have tags and well organized archives. I often do a search within when I'm looking for some JS stuff.
